摘要： A method is provided. A first enable signal is asserted so as to enable a first driver, where the first driver has a first output and a first parasitic capacitance. A second enable signal is asserted so as to enable a second driver, where the second driver has a second output and a second parasitic capacitance. The first and second outputs are coupled together by a switching network when the second driver is enabled. Pulses from complementary first and second radio frequency (RF) signals are applied to the first driver, where there is a first set of free-fly intervals between consecutive pulses from the first and second RF signals, and pulses from complementary third and fourth RF signals are applied to the second driver, wherein there is a second set of free-fly interval between consecutive pulses from the third and fourth RF signals.

摘要： Power amplifiers (PAs) using a Doherty or other power output level sensitive configuration have been employed for several years in telecommunications (as well as other applications) to take advantage of efficiency gains. For many of these applications, baseband signals are predistorted to compensate for nonlinearities in the PAs, but because there is a “switching event” in a Doherty-type amplifier (for example), the nonlinearities become dynamically varying. As a result, digital predistortion (DPD) becomes increasingly difficult to perform. Here, DPD modules are provided that adapt to changes in dynamically varying PAs based on a determination of the average power or other relevant metric prior to transmission.

摘要： Systems and methods for identifying a transmission channel response and a feedback channel response from a plurality of composite system responses are disclosed. A plurality of shifted feedback signals are created by shifting a feedback signal frequency by a plurality of first offset values and/or by shifting a transmission signal frequency by a plurality of second offset values. The feedback signals are compared to an input signal to identify the transmission channel response and/or a feedback channel response. A control signal is generated for a pre-distortion circuit to modify the input signal by an inverse of the transmission channel response. The composite system response is measured at a plurality of operating frequencies and at the plurality of offset values. The measurements are stored in a matrix and singular value decomposition is applied to the matrix of measurements to calculate the transmission channel response and feedback channel response.

摘要： Conventional transceivers do provide some compensation for in-phase/quadrature (I/Q) imbalance. However, these techniques do not separately compensate for I/Q imbalance for the transmitter and receiver sides of the transceiver. Here, a transceiver is provided that allows for compensation of I/Q imbalance in the transmitter and receiver irrespective of the other to allow for a more accurate transceiver.

摘要： A power on reset circuit includes: interconnected first and second inverter circuits; a capacitor connected to an input node of the first inverter circuit; and a buffer circuit responsive to voltage at an output node for generating a power on reset signal. In the power on reset circuit, in order to increase source voltage of an N channel MOS transistor in the second inverter circuit to a voltage higher than ground voltage, a diode-connected transistor is inserted between the source of the transistor and a ground node. Thus, the power on reset circuit never fails to produce the power on reset signal even when power supply voltage is dropped.
